MILK-CAN LOCK- Specification of Letters Patent.

Patented Sept. 11, 1.9116.`

.Application filed October 7,1905. Serial No. 281,838.

To all whom, t may concern:

Be it known that we, IGNATZ BERGER and ALBERT UHAZY, subjects of theEmperor of Austria-Hungary, residing at Allegheny, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Milk-Can Locks, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in locks,and the invention relates more particularly to a novel. form of lockadapted to be used in connection with milk-cans. K

The primary object of this invention is to provide a novel form of lockwherein positive and reliable means are employed for locking alid upon amilk-can, also means whereby a lid can be forced into engagement with acan to form an air-tight and nonleakable connection between the can andthe lid.

A further object of this invention is to provide a lock for milk-canswhich can be easily and quickly operated and manufactured at acomparatively small expense.

l/Vith the above and other objects in vieW the invention consists in thenovel construction, combination, and arrangement of parts to behereinafter more fully described and then Specifically claimed.

Referring to the drawings accompanying this application, like numeralsof reference designate corresponding parts throughout the several views,in which- Figure 1 is a front elevation of amilk-can equipped with ourimproved lock. Fig. 2 is a side elevation of the same. Fig. 8 is a planview of the can. Fig. 4 is a side elevation of the lid thereof. Fig. 5is a cross-sectional view of the lid, and Fig. 6 is a side elevation ofone end of a strap used in connection with the lock.

To put our invention into practice, we provide milk-cans withdiametrically-opposed yokes 1 1, these yokes being secured to the upperedge of the cylindrical body portion 2 of the can, as at 3 3. Theuppermost point of each yoke is enlarged to form a pierced boss 4. andbetween the bosses of the yokes is pivotally mounted a semicircular bail5. The pivoted ends of said bail are enlarged to form a cam-surface, asat 6 6, and these ends of the bail are provided with outwardlyextendinghook-shaped members 7 7, which pierced lug 10 and adapted to fitupon'ther neck portion of the can is a lid 11, said lid being formedwith a' central depending or countersunk portion 12, adapted to fitwithin the can. The lid is provided with depending sides 14 14, 'whichprovide an annu-' lar recess 15 for the reception of the upper end ofthe contracted neck 9 of the can'. In the annular recess 15 is placed` agasket or washer 16, adapted to form an air-tiglit and non-leakableconnection between the lid 11 and the can. The lid is also provided witha transversely-arranged bar 17, that is riveted, as at 18 18, to the topedges of the lid. The bar has its ends bent downwardly, as at 19, andprovided with outwardly-extending pins 20. The lid 11 is provided withan outwardly-extending pierced lug 21, said lug being formed with adepending lip 22.

When it is desired to lock the lid 11 upon the can, the bail 5 iselevated or raised to the position shown in dotted lines, Fig. 2, atwhich time the lid 11 is placed upon the contracted end of the can androtated until the depending lip 22 of the pierced lug 21 of the lidengages the pierced lug 10 of the can, the engagement of these lugscausing the openings of the lugs to register, also positioning the pins2O of the bar 17 to be engaged by the bail 5. The bail 5 is now swungover until the cam-surfaces 6 6 of the ends of the bail engage the pins20 20, this engagement forcing the pins downwardly, and consequently thelid, and a further movement of the bail causes the hook-shaped members 77 to pass around the pins 2O 20, the pins passing into thesegment-shaped slots 8 S. l/Vhen the bail has been placed in thehorizontal position, as illustrated in Figs. 1 to 3, inclusive, aconventional form of seal or lock can be employed for locking the bailand the pierced lugs 10 and 21 together, the seal passing through theopenings of said lugs and engaging around the bail 5.

l/Vhen the lid is locked upon the can, the transversely disposed bar 17serves as a handle or 01rip for carrying the can, it also being possibleto use the yokes 1 1 as handles when an extremely large can is to belifted. The countersunk portion of the lid permits of the bar 17 beingeasily gripped, at the same time providing a construction which ICO willinsure an air-tight connection being made between the can andthe lid.

. Attention 'is directed. to `the fact that were it not for thehook-shaped members 7 7 on the ends of the bail 5 and the lidmerely-held I down by the cam-shaped ends of the bail it would becomparatively easy to spread apart, as the' lid could be rotated lasufficient disf.

tance to throw the pins 20 `from under the ends of Ithe bail, landthiswould permit the revolving of the lid, even though -lugs 1'0,

itI is 'thoughtffrom ,the foregoing that .the construction,; operation,land-advantages. oit the herein-described'milk-,can lock will beyapparent without further description, i .andv

various, changes in l the iform, proportion, and minorfdeitails ofconstruction,'.,may,b e made Without departing yfrom .thespirit' of 'theinvention 'or sacrificing any of. the advantages thereof.

What we claim, and desire to secure by Letters Patent, isv Thecombination with la milk-can, diametrically-opposed yokes carried by thecan,

and an outwardly-extending pierced lug carried by the can, of a bailpivotally mounted in said yokes, said bail having camshaped ends andhook-shaped members carried by said ends, a lid, a strip carried by saidlid and having dependingends on `dia.-
